The interface strategy is to have a "distortion portal" opened at the current mouse coordinates when the mouse button is down.
接口策略是当鼠标键按下时，在鼠标当前坐标打开“失真门户”。

The MPM eliminates difficulty with mesh distortion as in the Lagrangian method, and with interface tracking and nonlinear convection term as in Eulerian scheme.
According to the interface procedure of the model transformation compiled in this paper, the finite element model was successfully transformed from CAD system to CAE system in "nought distortion".
